| Abstract: | Based on Chebyshev theory of function approximation to the interpolation for the nonstandard ellipse curve, the interpolating method with triple splint interpolation and bi-arc segment approximating mode is proposed for the middle bulged curve of piston in the motor. The formula of numeration used to machine programming is derived. The principle of bi-arc segment approximating mode is analyzed. According to the analysis of the error, the manufacture requirement is satisfied with the analyzed arc interpolating curves. |
